Specs side by side
What owners say
XT6
Overall
Mixed to negative sentiment overall, with a significant divide between initial appeal and long-term ownership experience. The vehicle is consistently praised for its comfortable ride, spacious three-row interior, attractive design, and strong value proposition when purchased at a steep discount or used. However, widespread and severe criticism centers on poor build quality, frequent mechanical and electrical failures, and outdated technology.
Best version to buy
Insufficient owner data available to identify a consensus "best" trim. The Sport trim and Platinum trim are mentioned, but feedback is focused on issues rather than trim superiority.
Known issues
- Poor build quality and premature squeaks/rattles: interior noises developing within the first few thousand miles. Frequency: very frequent.
- Mechanical and electrical failures: includes complete vehicle shutdown at an intersection, persistent no-start conditions, failing driver assistance system sensors, faulty rearview mirror displays, and failing liftgate hydraulics.
- Outdated and problematic infotainment system: described as technology from circa 2016, with constant pop-up messages that must be cleared, laggy response, and an obnoxious user interface. Frequency: very frequent.
Telluride
Overall
Mixed to positive sentiment overall, with a clear generational divide. The Telluride is widely praised for its spacious and functional third row, high-quality interior materials, boxy and attractive exterior styling, strong value proposition, and comprehensive standard features. The naturally aspirated 3.8L V6 engine is frequently cited as a mature, reliable, and simple powertrain, especially when compared to newer turbocharged or hybrid alternatives.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim. Discussions mention various trims (SX, EX, Calligraphy) without a clear, repeated preference for one over another.
Known issues
- Engine oil consumption: reports of excessive oil consumption requiring top-ups between changes and, in isolated cases, engine replacement. Frequency: recurrent.
- Underpowered 3.8L V6 engine: described as lethargic, slow, lacking responsiveness, and struggling with acceleration compared to turbocharged rivals. Frequency: very frequent.
- Dealer/service department problems: poor customer service, difficulty getting warranty repairs approved, lack of respect for customers, and general service quality concerns. Frequency: very frequent.
